Electrons move from Sphere A to Sphere B.
Explanation: The negatively charged rod induces polarization in the touching neutral spheres, repelling electrons away from the rod toward the farther sphere (B). This is charging by induction (redistribution), not by friction or by electrons coming from the rod.
